Design a Logo for Company & Products

Résumé de concours

I am after a logo for my company use and to be used with products. The main logo image will not change however the text underneath will depending on the 'brand' it is being used for. Ie Wicked Candle Co. for our range of candles, Wicked Australia Pty Ltd for company invoices ect. The main products the logo will be used for are candles and skin care. Wanting a very premium / elegant feel.
I want to go for a 'French design', possible round(ish), and somehow encorporate the four elements into the logo design (Earth, Wind, Water & Fire).
I would like a unique font, but something that is easy to read.
Under the logo image and above the text I would like a thin line (band) of rainbow colours (Red, Orange, Yellow, Green, Blue, Purple).
As the logo image and band of colour will form the logo, I would want to be able to change the main text as required to suit the branding it is being used for.
Please ask for further clarification
